- 1. Technical field
- The present disclosure relates to a surgical access port. More particularly, the present disclosure relates to a surgical access port including a securing member configured for securing the surgical access port relative to tissue.
- 2. Related Art
- Surgical access port devices, such as introducers, trocars, cannulas, and so forth are commonly known in the medical art and permit the introduction of a variety of surgical instruments into a body cavity or opening of a patient. In procedures, such as endoscopic or laparoscopic surgeries, an incision is made in tissue for access to an underlying surgical site in the body. These procedures typically employ surgical instruments which are introduced into the body through the port positioned with an opening in tissue. In some instances, the port may be removably secured within the opening in tissue via one or more structures, e.g., a balloon or other suitable structure(s) that is insufflated with a suitable fluid, e.g., saline. In this instance, when the balloon(s) is sufficiently insufflated with the fluid, the balloon engages a body wall or tissue to generally fix the port within the tissue.
- Accordingly, a surgical access port apparatus includes a portal member having an outer wall defining a longitudinal axis and a proximal end, a distal end, and a lumen configured to allow a surgical instrument to pass therethrough. A securing member is operatively connected to the distal end of the outer wall of portal member. The securing member is movable with respect to the portal member between an initial at least partially coiled condition defining a first transverse dimension and an activated condition defining a second transverse dimension greater than the first transverse dimension to engage body tissue to assist in retaining the portal member within the body tissue.
- The securing member may be a spring member defining a coiled configuration in at least the initial condition of the securing member. The spring member is at least partially disposed within the lumen of the outer wall of portal member when in the initial condition of the securing member. The spring member may be operatively coupled at one end thereof to the outer wall. The spring member may define an expanded coiled configuration when in the activated condition of the securing member.
- A recapture instrument may be dimensioned for passage within the lumen of the portal member. The recapture instrument may be configured and adapted to engage the spring member, and return the spring member to the initial condition of the securing member. The recapture instrument may include an elongated member having a spring receiving slot dimensioned to receive a spring segment of the spring member, and may be manipulable whereby the spring receiving slot cooperates with the spring member to return the spring member to the initial condition of the securing member. The recapture instrument may be adapted for rotational movement relative to the outer wall of the portal member whereby with the spring segment within the spring receiving slot of the recapture instrument, relative rotational movement of the recapture instrument will cause the spring member to recoil and return to the initial condition. The distal end of the recapture instrument may be dimensioned for passage through tissue.
- In an alternative embodiment, the spring member is mounted about the distal end of the portal member when in the initial condition of the securing member.
- A method of performing a surgical procedure, includes the steps of:
-
- introducing a portal member within tissue to provide access to an underlying body site, the portal member having a spring retaining member operatively coupled thereto;
- deploying the spring retaining member relative to the portal member to cause the retaining member to transition from an initial at least partially coiled condition defining a first transverse dimension to an activated condition defining a second transverse dimension greater than the first transverse dimension whereby the spring retaining member engages body tissue to assist in retaining the portal member within the body tissue;
- passing a surgical object through the portal member: and
- performing a surgical task with the surgical object.

- With reference to
FIG. 1 , a surgical access port apparatus in accordance with the principles of the present disclosure is shown, designated asreference numeral 10. Surgicalaccess port apparatus 10 includes a body portion orportal 20 and securing structure ormember 40. Surgicalaccess port apparatus 10 may be any device suitable for the intended purpose of accessing a body cavity, such as a trocar or cannula, and typically defines a passageway permitting introduction of surgical instrumentation therethrough. Instrumentation includes a variety of surgical devices utilized through a portal, such as those used during laparoscopic or endoscopic surgery, as is within the purview of those skilled in the art. -
Surgical access port 10 may be used in a variety of surgical applications and is particularly adapted for use in laparoscopic surgery where the peritoneal cavity is insufflated with a suitable gas, e.g., CO2, to raise the cavity wall from the internal organs therein.Surgical access port 10 includes asecuring member 40 having one or more retractable coiled rings or springs that may be deployed to anchor thesurgical access port 10 into the surrounding tissue to prevent removal or retropulsion of theportal 20 in the presence of a pressurized body cavity, e.g., an insufflated abdominal cavity. - Portal 20 may be a single monolithically formed unit or composed of several components connected to each other through conventional means, such as, for example, ultrasonic welding, or any other means envisioned by one skilled in the art. Portal 20 may be formed of any suitable medical grade material, including metals such as stainless steel, titanium, and aluminum; other rigid materials, including polymeric materials such as polyetheretherketones, polycarbonate, polypropylene, polyethylene, and composites thereof. Portal 20 may be manufactured for a single use or can be sterilized and reused.
- Portal 20 includes
outer wall 22 havingproximal end 24 anddistal end 26.Outer wall 22 defines a longitudinal axis “x” extending along the length ofbody portion 22 and defines an internal longitudinal passageway orlumen 25 dimensioned to permit passage of surgical instrumentation (not shown).Outer wall 22 includes a generally circular configuration which forms the longitudinal passageway orlumen 25 whereby other surgical instruments may be placed such thatbody portion 20 aids in the insertion of instruments, implants, and other surgical related apparatus. Further, the shape ofouter wall 22 may provide stiffness toouter wall 22 so that it will not bend under the counter force of tissue.Proximal end 24 may include a housing or the like and may incorporate one or more seals for establishing a seal about an inserted object instrument or to close thelumen 25 in the absence of the surgical instrument. - Referring now to
FIG. 2 , a securing structure in the form of aretractable coil spring 42 is shown operatively disposed on theportal 20. More particularly,spring 42 operatively couples to adistal end 26 ofbody portion 22.Spring 42 includes asecuring end 44 that connects to thedistal end 26. More particularly, securingend 44 operably couples to astructure 40 ofouter wall 22 having proportional dimensions. In the embodiment illustrated inFIGS. 1-5 , thestructure 40 is in the form of a slot or slit 40 within outer wall that is configured to couple to the securingend 44 ofcoil spring 42 via a press fit or friction fit. In embodiments,spring 42 or portion thereof may include other suitable connection structures and or devices (e.g., adhesives, welding, screws or other mechanical fixing mechanisms) configured to secure thespring 42 within the distal end of the portal 20. -
Spring 42 is movable from an initial coiled condition to an activated condition. In the activated condition, thespring 42 is configured to securely engage tissue surrounding an opening. In the embodiment illustrated inFIGS. 1-5 ,spring 42 is shown coiled at adistal end 26 at least partially withinlumen 25 ofbody portion 22. Alternatively,spring 42 may be wrapped (e.g., coiled) around an outer peripheral surface of thebody portion 22. -
Spring 42 includes dimensions of suitable proportion with respect to thedistal end 26 ofbody portion 22. More particularly, in an initialcoiled condition spring 22 includes “n” number of turns and includes a first transverse dimension or outer diameter “Dl” that is less than an inner diameter of thebody portion 22 and/or at least an inner diameter of the distal end 26 (seeFIG. 3 , for example). The number of turns “n” thatspring 42 includes when thespring 42 is in the initial, coiled condition may depend on a number of variables, such as, for example, the length and/or width of thespring 42, the desired outer diameter “D2” of thespring 42 when thespring 42 is in a subsequent, activated condition, and so forth. The number of turns “n” thatspring 42 includes is directly proportional to the amount of force that thespring 42 will exert on the walls of the opening in tissue when thespring 42 is in the uncoiled condition and positioned in the opening in tissue. That is, the greater the amount of turns “n” of thespring 42 the greater the force thespring 42 will exert on the walls of the opening in tissue.Spring 42 includes a second outer dimension or diameter“D2” that is greater than an outer diameter of thedistal end 26 of thebody 22 when thespring 42 is in the subsequent, uncoiled condition (seeFIG. 4 , for example).Spring 42 includes a width “w” that is uniform along a length of thespring 42. By increasing the width “w” of thespring 42 the more surface area of thespring 42 is available for gripping tissue, which, in turn, provides a securer and/or tighter fixation of thesurgical access port 10 when thespring 42 is in the subsequent, activated and within the opening in tissue. In the alternative,spring 42 may have a circular cross-section. -
Spring 42 may be formed from any suitable resilient material. For example, in one embodiment,spring 42 is formed from spring steel, shape memory material such as Nitinol or the like.Spring 42 is normally biased to the activated condition ofFIGS. 4 and 5 and has sufficient flexibility to be restrained within thelumen 25 of theouter wall 22 in the initial condition of thespring 42. In the activated condition, the coils ofspring 42 at least partially unwind to increase the dimension of thespring 42. In embodiments, one or more elements or compounds, such as, for example, carbon or low-alloy steel may added to the spring steel to give it the hardness and yield strength needed in springs so that the steel may return to its original shape after uncoiling, bending, twisting, or other deformation. - A method of use of
surgical access port 10 will now be described. Initially,spring 42 is in the initial coiled condition at least partially within body portion 26 (FIG. 2 ).Portal 20 may be inserted into an opening, e.g., such as an incision in tissue of a patient, withproximal end 24 available for manipulation by the operator anddistal end 26 submerged within the opening in a patient. Once positioned within the opening of a patient,spring 42 is caused to deploy fromdistal end 26 ofportal 20 to grip or otherwise grasp the surrounding walls of the opening in tissue. In embodiments, one or more types of surgical instruments (e.g., anintroducer rod 50 depicted inFIG. 4 ) may be employed to deploy or “push” thespring 42 from thedistal end 26 of the portal.Spring 42 in the deployed and actuated condition ofFIGS. 4 and 5 will engage surrounding tissue to securebody portion 22 relative to the tissue. Thereafter, a surgical task may be performed within the underlying body cavity with aninstrument 1000 introduced throughlumen 25 as depicted inFIG. 5 . Subsequent to the performance of the surgical procedure, thespring 42 will be returned to its initial condition. In one embodiment,outer wall 22 ofportal 20 may be rotated in one direction (e.g., counterclockwise) as shown by directional arrow “F” inFIG. 5 . As theouter wall 22 rotates, thespring 42 may be drawn back into thelumen 25 ofouter wall 22 and assume the initial condition confined within theouter wall 22. - From the foregoing and with reference to the various figure drawings, those skilled in the art will appreciate that certain modifications can also be made to the present disclosure without departing from the scope of the same. For example,
surgical access port 10 is typically used with an obturator assembly 100 (FIG. 6 ) that includes adistal end 102 which may have a blunt, non-bladed end or sharp, bladed end positionable within the passageway ofsurgical access port 10. Theobturator assembly 100 is positioned within theportal apparatus 20 and is utilized to penetrate the abdominal wall. Theobturator assembly 100 may then subsequently be removed fromsurgical access port 10 to permit introduction of surgical instrumentation utilized to perform the procedure through thelumen 25. Accordingly, in embodiments, it may prove useful to provide anobturator assembly 100 and/ordistal tip 102 associated therewith that may be utilized to both deploy and/or retract thespring 42. More particularly, thedistal tip 102 of theobturator 100 may be configured to recoil and/or retract a securing member associated with the device 10 (seeFIG. 6 , for example). In this instance, thedistal tip 102 may include a generally rounded, circular cross-section that extends along a portion of thedistal end 102. The rounded, circular cross-section facilitates deploying thecoil spring 42 from thedistal end 26 of thebody portion 22. That is, thedistal tip 102 includes a surface area that is proportioned to force thecoil spring 42 distally from thedistal end 26 of thebody portion 22. A notched or slottedportion 104 is operably disposed along a length of thedistal end 102. More particularly, the notchedportion 104 may be configured to “hook” and “rotate” thespring 42 such that an operator may recoil and subsequently retract thespring 42 back into thedistal end 26 of thebody 22. To this end, the notchedportion 104 includes a proximalhemispherical sidewall 108. A generallyflat surface 110 extends distally from thehemispherical sidewall 108 to adistal sidewall 112 and includes two pronounced side edges 110 a and 110 b. Anoverhang 114 extends from thedistal sidewall 112 and is defined by an outer peripheral surface of thedistal tip 102 of the obturator. The combination of the proximal anddistal sidewalls overhang 112 facilitates in engaging and receiving a segment ofspring member 42 as shown inFIG. 7 . Theobturator 100 may be rotated in, e.g., a counterclockwise direction “k” and simultaneously moved in a proximal direction “t” to recoil and draw thespring 42 withinbody portion 22 as depicted inFIG. 7 . - It is further contemplated that an
activation component 46 may be operably connected to an actuating member 48 (shown in phantom inFIG. 1 ) and configured to deploy and/or retractspring 42 fromportal 20. With this purpose in mind,activation component 46 is accessible to an operator atproximal end 24 ofportal 20.Activation component 46 and actuatingmember 48 may be monolithically formed or connected to the portal 20 by means within the purview of those skilled in the art. In embodiments,activation component 46 may be a button, plunger, tab, trigger, or other activation component within the purview of those skilled in the art to help distally and/or proximally translate actuatingmember 48 with respect toportal 20. Actuatingmember 48 is mechanical communication withcoil spring 42 and is configured to deployspring 42 for fixation into an opening in tissue. Actuatingmember 48 may also configured to recoilspring 42 to its initial, coiled condition and, if needed, retractspring 42 back within thebody portion 42. - It is contemplated that in embodiments in which
portal 20 is used with laparoscopic procedures,surgical access port 10 may also be configured to seal the body opening to maintain the pneumoperitoneum while permitting the introduction of surgical instrumentation. For a more detailed description seals or seal assemblies suitable for use with thesurgical access port 10 of the present disclosure reference is made to commonly owned U.S. Pat. Nos. 6,702,787 to Racenet et al., 6,482,181, also to Racenet et al. and 6,551,282 to Exline et al. contents of which are hereby incorporated by reference in their entirety. -
FIG. 8 illustrates an alternate embodiment of the securing member of the present disclosure. Securingmember 500 is substantially similar to the securing member ofFIGS. 1-7 ; however, in accordance with this embodiment, securingmember 500 is positioned overcannula member 502 and enclosed within anouter sheath 504.Sheath 504 is retracted relative tocannula member 502 to expose the securing member for deployment and engagement with the tissue. Securingmember 500 may be secured tocannula member 502 by any mechanical or adhesive means. An instrument may be advanced withincannula member 502 to perform the desired surgery. Securing member may be retrieved or moved to the initial condition by advancing theouter sheath 504 over thecannula member 502 to thereby constrain the securingmember 500 within the confines of thecannula member 502. - It will be understood that various modifications may be made to the embodiments disclosed herein. Therefore, the above description should not be construed as limiting, but merely as an exemplification of preferred embodiments. Those skilled in the art will envision other modifications within the scope and spirit of the present disclosure. Such modifications and variations are intended to come within the scope of the following claims.
